Hey guys! I'm learning C++ and everything is... was ok. hahaha. I wanted to do a class SquareMatrix and in the constructor get a N integer to create my matrix NxN.

In java that would be:

class SquareMatrix{

     private int matrix[][];
 
     SquareMatrix(int n){
          matrix = new int[n][n];
     }
}

But in C++ I can't do this, and can't find a way to do it. Help neede plz! Thank you in advance!

code:

---

class SquareMatrix{
public:
    SquareMatrix(int n);

private:
    int matrix[][];
}

SquareMatrix::SquareMatrix(int n) {
    matrix = new int[n][n];
}

Get a book

Edit: [code] should also turn on [noparse]

Thanks raceprouk but it didn't work. I get this error with your code.

"In file Matrix.h declaration of matrix as a multidimensional array must have bounds for all dimensions except the first."

I thought about it, it was like the translation between Java and C++ but it looks like it doesn't work like that in C++, I have some books and a lot of articles on C++, but can't find something like this.

Can you tell me which line the error is on?
